In a 2009 interview, Gallagher told the following anecdote:
This writer, he was going on about the lyrics to "Champagne Supernova", and he actually said to me, "You know, the one thing that's stopping it being a classic is the ridiculous lyrics." And I went, "What do you mean by that?" And he said, "Well, 'Slowly walking down the hall, faster than a cannonball' — what's that mean?" And I went, "I don't know. But are you telling me, when you've got 60,000 people singing it, they don't know what it means? It means something different to every one of them."
Not that I’m one to normally defend the Gallaghers... but I guess he has a point.
